CUPEL-MAGHINE.

SPECIFICATION forming part of Letters Patent No. 641,208, dated January 9, 1900.

Application filed May 27,1898. $erial No. 681,888. (No model.) 7 7 clear, and exact description of the invention,

such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the figures of reference marked thereon, which form a part of this specification.

My invention relates to improvements in machines for manufacturing cupels; and it consists of the features hereinafter described and claimed, all of which will be fully understood by reference to the accompanying drawings, in which is illustrated an embodiment thereof.

In the drawings, Figure 1 is a partial sectional side elevation of myim proved machine, partly broken away. Fig. 2 is an endview of the same. Fig. 3 is a fragmentary section taken through the upper part of the device. Fig. 4 shows a side and end view of a sleeve inserted in the mold or matrix for diminishing the size of the cupel. Fig. 5 is a section taken through the base of the machine, showing one of the supporting-rods in place.

Similar reference characters indicating corresponding parts in the views, let the numeral 5 designate the base, and 6 the top casting of the machine. The two castings are connected by two rods 7, whose extremities are secured in place by set-bolts 8, inserted in threaded openings formed in the castings at right angles to the sockets in which the rod extremities are inserted. The lower extremities of these rods 7 enter openings 5, extending through the base 5. (See Fig. 5.) By adjusting these rods in the openings 5 the distance between the top and bottom castings may be changed at will. Between the two rods is located a vertically-reciprocating bar 9, whose lower extremity engages a suitable socket formed in the base 5. This bar is raised in the operation of forming the eupel by means of a foot-lever 10, fulcrumed on the base, as shown at 12. The lower extrem ity of the bar 9 rests on the inner and shorter tened part 14.

provided with a detachable sleeve 14, held in place by a pin 15, attached to the casting and projecting into a circular groove 14;, formed in the sleeve, which is flattened, as shown at 14, below the groove to allow the sleeve to be inserted in the matrix from above. When the sleeve is in place, it is locked by turning it until the pin '15 is out of line with the flat- The upper extremity of the matrix is closed by a cap 16, pivotally attached to the casting by a bolt 17. When this cap is swung to one side, the cupel may position closing the top of the matrix, after which the bar 9 and its die 13 are thrust upwardly by pressing on the outer arm of the foot-lever 10. The recess or cavity in the cupelis thus formed by the die. The cap is then turned to open the top of the matrix, after which the cu pel is ejected or thrown out of the matrix by further upward movement of the die and the bar 9. The downward movement of the bar 9 is accomplished by gravity. As it moves downwardly, it engages the inner arm of the foot-lever 10 and raises the outer arm of said lever. To this end the said bar is made of sufficient weight to accomplish the said function. The downward movement of the bar is limited by an adj ustable collar 18, held in place on the bar by a set-screw 19.

When it is desired to form a larger cupel, the sleeve 14: is removed and a larger die or one corresponding to the size of the matrix attached to the upper end of the bar.

Having thus described my invention, what I claim is 1. In a cupel-machine, the combination of the base and top castings provided with openings, two rods, whose extremities engage the openings in the castings, set-screws entering the castings and arranged to fasten the rods in place, a vertically-movable bar located between the rods and engaging a socket in the base, the upper extremity of the bar being formed into a die, the top casting being provided with a matrix which the die extremity of the bar is adapted to enter, a lever fulcrumed on the base and adapted to engage the lower extremity of the bar, which rests thereon, and a cap movably mounted on the top casting and adapted to close the top of the matrix.

2. The combination of the base containing a socket, a lever fulcrumed on the base and projecting into the socket, a top containing a matrix, connecting-rods entering openings formed in the top and base, means for fastening the rods in place,whereby the distance between the top and base may be regulated at will, a vertically-reciprocating bar engaging the socket in the base, and provided with a die adapted to enter the matrix of the top, the lower extremity of the bar lying in the path of the inner arm of the lever, and a cap movably attached to the top of the device and adapted to close the matrix.

3. The combination of the top and base, the top containing a matrix, and the base a socket in line with the matrix, a sleeve detachably applied to the matrix for limiting its size, a lever fulcrumed on the base and projecting into the socket, a vertically-movable bar engaging the socket in the base and lying in the path of the inner arm of the lever, a die attached to the upper extremity of the bar and adapted to enter the matrix, two adjustable rods for connecting the top and base, whereby the distance between them may be regulated at pleasure, and a suitable cap applied to the top of the device and arranged to swing on a vertical axis to open and close the matrix.

at. The combination ofthe base containing a socket, a lever fulcrumed on the base and projecting into the socket, a top containing a matrix, a suitable connection between the top and base, a vertically-reciprocating bar engaging the socket in the base and provided with a die adapted to enter the matrix of the top, the lower extremity of the bar resting on the inner arm of the lever, whereby the said arm is raised by the lever, its downward movement being accomplished by gravity,

the bar being of suflicient weight to return the lever to its normal position.

In testimony whereof I affix my signature in presence of two witnesses.
